@shade I've aborted and retried several times but that doesn't work out. Install it do a different hard drive. I'll let you know if that helps. UPDATE: Even with a different install location the errors still come up. I hit ignore and one after another more of the data files pop up and I have to hit ignore several more times.

Phantasy Star Universe should be in a different directory from Ambition of the Illuminus (by default, they installed to "C:\SEGA\PHANTASY STAR UNIVERSE" and "C:\SEGA\PHANTASY STAR UNIVERSE Illuminus"). They're not actually cross-compatible.

I tried running the patch for PSU, but no matter what I do, I keep getting this error message that the PATCH file cannot be found. What am I doing wrong? Here are some pictures of what I see.https://imgur.com/gallery/WwCbO

I've tried right now to patch a fresh installation of JP PSU with the self-extracting 7zip archive, and it worked fine on my computer (W10).

Wait. I have an OG version (DVD-ROM) of PSU (And AotI). Does that affect anything?I'll in the meantime try to reinstall in a different directory and download the self-extracting patch instead.

EDIT : I reinstalled under the same C//: memory but not into the Program Files (x86) this time, however to no surprise, the result was the same. What else might be causing the patch to not find the file? Any ideas?
